HPE 850887-B21 Apollo d6500 Server Node Blank Kit
HPE 850887-B21 is an Apollo d6500 Server Node Blank Kit designed for the HPE Apollo 6500 chassis. It fills an unoccupied server-node slot when a server tray is not installed, supporting the chassis airflow and thermal-management design. HPE specifies the blank as required for non-populated slots and for Advanced Power Manager 1.2 or 2.0 deployments. This makes 850887-B21 a chassis-management accessory rather than a compute, storage, or networking component.
